<P>PROBLEM TO BE SOLVED: To provide processing for attenuating a noise of a fluorographic image in order to make the fluorographic image more clear. <P>SOLUTION: The processing method and the system for improving a digital image of an object collected at a time point t from an X-ray detector to receive X-rays emitted from an X-ray source and regulated by prepared pixels are provided. The processing method includes a process to determine an estimation image of an object at a time point t as the function of an image of the object collected at a point of time t-i (wherein i is a positive integer of ≥1 ), a movement process to move respective layers constituting an image collected at a point of time t wherein the number of the layers is determined beforehand and movement relevant to respective layers is determined beforehand, and a process to prepare a visual image corresponding to the weighted sum of the estimation image and the image collected at the point of time t in order to attenuate noise of the image of the object collected at the point of time t. <P>COPYRIGHT: (C)2007,JPO&INPIT |
